WIND-SHIELD FOR I-IARVESTERS.

To all whom it may concern:

, Be it known that I,.VVIJ;.LIAM H. CRANE, a citizen of the UnitedStates, residing at Poughkeepsie, in. the county of Dutchess New York,have invented certain new and useful Improvements inind- Shields fortherein to the accompanying drawing.

This invention relates to harvesting machines, and is. concerned moreparticularly with the wind-shield or wind-break which is sustainedadjustably in an upright posi tion over the grain: platform and parallelwith the finger bar, to prevent the .wind from interfering with theproper fall of the grain on the platform When severed by the knives. 1

My invention consists of a construction of improved form and arrangementfor maintaining the wind-shield in operativerelation to the platform andfinger bar, and for quickly and conveniently adjusting it to and fromthe finger bar, to meet the varying conditions encountered in practicewith respect to the length of grain being harvested.

In the accompanying drawings:

Figure 1 is a top plan view of a portion of the main frame and theplatform frame of a harvesting machine havingmy' invention appliedthereto, the wind-shield being shown in its rearward position toaccommodate long .grain.

Fig. 2 is a similar view with the windshield adjusted to a forwardposition to accommodate short grain.

Fig. 3is a top plan view on an enlarged 1 scale of a portion of themachine frame and the adjacent connected parts sustaining thewind-shield. Y

- Fig. 4 is a verticaljsectional elevation on the line a-aof Fig. 3. vFig. 5 is a similar view on the line b'b of Fig. 3.

Referring to the drawings;

the platform and sustains a drivers seat 6 by means of a seat springbracket 6.

I indicates a wind-shield or wind-break consisting as usual of a flatrectangular screen or board which is sustained in an upright positionover the grain platform, parallel with the finger bar, and servestoshield the falling grain from wind currents so that it will be properlydeposited on the platform carrier. V

y invention is directed to the means for sustaining the wind-shield sothat it may be moved or adjusted horizontally to and from the fingerbar, and be maintained in all of its positions of adjustment, parallelwith the finger bar.

In accordance with my invention the windshield is pivoted between itsends to the outer end of a hanger arm 8 on a vertical axis formed by avertical pivot bolt 9 extending loosely through the end of the arm andinto the top bar of the wind-shield. At its inner end the hanger arm hasfixed to it a strap or plate 10, the end of which projects beyond theend of the arm in the form of a finger 11 which is extended beneath theseat supporting member and is pivoted thereto on a vertical axis bymeans of a spring 6 and a seat vertical pivot bolt 12 extending throughthe seat supporting member and the finger. The weight of the arm in itsswinging movements on the bolt 12, is sustained by a brace bar 13, theupper end of which is provided with a depending journal 13 mounted in abearing in the seat-spring bracket in vertical alinement with the axisof the bolt 12, and the lower end of which is firmly connected to thestrap 10. As a result of this construction, the hanger arm is free toswing horiand relatively to the frame on a vertical axis situated at theinner end of the arm, and the windshield is free to swing relatively tothe outer end of the arm about a vertical axis parallel with the firstmentioned axis, the result being that the. shield may be moved in a foreand aft direction over the platform to and from the finger bar from arear position asshown in Fig. 1 to a forward position as shown in Fig.2. 3

In order that in these movements of the windshield it will be caused tomaintainits parallelism with the finger bar, a link 11 is provided whichextends in rear of the hanger to pro] arm and parallel therewith, theinner end of the link being provided with a depending journal 15'mounted in a vertical bearing in the seat supporting member, rearward ofand in line with the pivotal axis of the hanger arm, and the outer endof the link being provided with a dependingjournal 16 mounted in abearing in the rear end of a horizontal bracket 17 fixed to andprojecting rearwardly from the wind-shield, the said bearing being inrear of and directly in line with the pivotal connection of the outerend of the hanger. arm with the wind-shield. The hanger arm and linkthus form-in effect a parallel movement which, while permit-J ting theparts to swing about their respective axes in the movements of'thewindshield to and from the finger bar, will maintain the wind-shieldatall times parallel with the finger bar. I V

In order that the movements of the hanger arm may be convenientlycontrolled by the driver, and in order that the parts may be releasablylocked against movement to hold the wind-shield in its differentpositions of adjustment, I provide'a locking latch in the form of ahorizontal latch bolt 18 which is mounted to slide back and forth in alatch casing 19 fixed to the upper side of the hangerarm adjacent itsinner end. 7 The outer end of the latch bolt is provided with a verticalactuating arm '20 extending upwardly above the latch casing so that itmay be conveniently operated by the drivers foot, the said arm in themovements of the latch bolt sliding between the walls of a slot 21 inthe end of the casing by which means the arm is maintained in an uprightposition. The latch bolt is. acted on by a spring 22 encircling the sameandbearing at one end against the end of the casing and'at its oppositeend against a pin 23 fixedto the latchbolt, the'tendency of the springbeing 'ect the latch boltinwardly and maintain it yieldingly in alockingposition as shown in Figs. 3 and 4. The inner end of the bolt isformed with a locking tooth 24: adapted to enter any one of a series ofnotches 25 in the edge of a horizontal segment plate 26, the inner endof the plate being provided with an opening 27 through which the journal' 15' on the end of the link 14 extends, and by which it" ispivoted to the" seat sustaining member on a, vertical axis coincidentwith the axis of the connection of the link 14 therewith. At its freeend the segment plate slides through and 1s guided in a horizontal slotor opening 28 in the latchcasing in such position that in the relativemovement of the parts, the notches receive thelocking tooth on the latchbolt. When the locking tooth is engaged in one oft-he notches as shownin Fig. 3, the parts will be locked in position and held against hangers' y of adj usting" the found in practice to 111 the plate Wlll bepresented in position to was adjusted; but when the tooth is disengagedfrom the notch, the parts will be free to be swung about theirrespective, axes, the segment plate in such movement sliding through theguiding opening in the" latch casing, with the notches in the plate inposition to be'engaged by the locking tooth.

In the operation of the mechanism by the driver to adjust the positionof the windshield he places his foot on thevertical actuating arm of thelatch bolt and slides the bolt endwise against the pressure'of thespring, the locking tooth. being by this action disengaged and leavingthem free to be swung about ward toward the finger bar, the driver,while holding the latch disengaged, pushes for ward with his foot andthereby swings the arm 7 forward, which correspondshifts the shield inlike direction. hen the shield has been thus adjusted to its properposition, the pressure of the-foot on the latch bolt 18 relieved, andthe spring acting, will seat the looking toothin one from the'notch inwhich it was seated and thereby unlocking the parts of the notches inthe segment plate and-the parts will thus be locked firmly in position.To adjust the shield in the opp'oslt'e direction, the foregoing'actionsare repeated, but

the hanger arm is movedby'the drivers foot rearwardly instead offorwardly. I

By the employment of the notched segment plate pivoted to the framemember and guided on the hanger arm in position to be engaged by thelatch, flexibility of "movement is given to'the parts inthe operationsame, and the latch is enabled to engage with certaintyrbetween thenotches without requiring a very close or accurate fit of the parts. Theupwardly. extending actuating arm on the latch bolt movable horizontallyin controlling the looking and unlocking of the latch, affords a veryconvenient means for operationby'the foot of the driver, the continuedpressure of the foot on the actuating arm, exertedin either directionafter the latch is unlocked,

causing the hanger'arm to be moved back and forth and the windshield tobecorrespondingly' moved; The adjusting operation is thereforeconveniently effectedyand direct and certain in itsfacti'on.

In the foregoing description and-accompanying drawings Ihave set forthmy'invention in the particular detailedi form 7 and construction ofthe'fparts which I have tory degree the ends to be; attained. It'will bemanifest, however, that these details may be; variously changed andmodified' without departing from the answer to'a satisfac-' H limits prmy invention, provided the operation will be substantially as abovedescribed; and it Will be understood that the invention is not limitedto any particular form or construction of the parts except in so far assuch limitations are specified in the claims.

Having thus described my invention, what I claim is:

1. In a harvester, the combination of a frame, a grain platform thereon,a hanger arm pivoted to the frame and extending above the platform, awind-shield pivoted to said arm, a link pivoted to the frame andwind-shield respectively, a plate pivoted to the frame on the pivotalaxis ofthe connection of the link therewith and extending adjacent thehanger arm, and a releasable locking latch on the hanger arm in positionto engage the plate and look the parts in position.
